Definitions

  • This disclosure relates to beverage cooling systems. More particularly, this disclosure relates to a modular beverage cooling system having modules that are independently removable from and connectable to the remainder of the main assembly.
  • a conventional beverage cooler contains all the major refrigeration components, such as compressor and evaporator, integrally within a single cooler carcass.
  • the refrigeration system is configured so that the evaporator is contained in a waterbath and the other refrigeration components are situated in an area commonly referred to as the "fridge compartment".
  • the evaporator is hermetically connected to the other refrigeration components most commonly by rigid copper or stainless steel pipework, via permanent or semi-permanent soldered or brazed joints. Therefore, the fridge compartment and waterbath are essentially inseparable in service, other than by a service person skilled and trained in the art of refrigeration, and having all the necessary specialist equipment to safely carry out the operation.
  • the cooling capacity is determined by the size, or displacement of the compressor. It is not possible to increase the cooling capacity of an installed beverage cooler. So, if a conventional cooler is correctly sized to suit a trading account at the time of installation, it may not have sufficient capacity to accommodate a significant increase in drinks sales in a future changing market. It does not make financial sense, both from an acquisition cost or energy consumption perspective, to install over-sized coolers where sales do not warrant it at the time of installation. Likewise, a long-term downturn in sales could leave an end user with a cooler that is over-sized for the prevailing market, incurring higher than necessary energy costs and wasted capacity. The preferred solution in both circumstances may be to replace the existing cooler with an alternative cooler more appropriately sized for the new trading environment. This is a costly and disruptive operation, usually requiring two service operatives and significant downtime.
  • conventional beverage coolers are designed and constructed with a specific refrigerant type included.
  • the refrigerant type may be a customer preference, or may be dictated by environmental regulations. Once constructed and commissioned, it is unlikely that a change of refrigerant would be feasible during an individual cooler's operational lifetime. So, any change in a customer's preference, or further environmental legislation against an existing refrigerant, or even a new refrigerant entering the market with significant advantages over the current range of refrigerants could mean an entire population of beverage coolers might have to be replaced, simply to accommodate a change of refrigerant.
  • the conventional beverage cooler is installed in a predetermined space within the trading account. In many cases, this space may be unsuitable for a variety of reasons.
  • the conventional beverage cooler may be sited in a very restrictive area, where air circulation is poor; this may compromise the efficiency and performance of the conventional beverage cooler, and may result in premature component failure, high energy consumption, or repeated service calls for warm drinks.
  • the conventional beverage cooler could be sited in an area where excessive heat or cold is experienced for large parts of the day; these extremes may also impact on performance, energy consumption and reliability. Little can be done to alleviate these conditions, once the conventional beverage cooler is installed and commissioned.
  • a modular beverage cooler that has a refrigeration module, a pumping and control module, and a beverage cooling module that are independently removable from and connectable to the remainder of a main assembly.
  • a modular beverage cooler that has a second cooling medium that is circulated in a cooling tank and that is cooled by a refrigeration system having a first cooling medium.
  • a modular beverage cooler that has a first refrigerant that flows into a condenser or gas cooler where the first refrigerant is cooled by a fan, and a second refrigerant that is cooled by the refrigeration system that is circulated by a pump where the pump and the fan are operated by the same motor.
  • WO 2007/029074 describes a deverage cooling system having the features as defined within the preamble of claim 1; document GB 2 480 861 discloses a similar beverage cooling system that disposes of at least two refrigeration systems for cooling with a single cooling fluid a space cooler and a chill tank.

  • Heat exchanger coil 6 is connected to an interior wall 104 of tank 5.
  • Tank 5 has valves 106 that connect a flow of the beverage ingredient with cooling coils 4.
  • Valves 106 may be connected to a manifold 107 so that valves 106 are removable from manifold 107. Valves 106, for example, are positioned in a John Guest® shut-off valve manifold.

  • the secondary medium may consist of a solution of water and anti-freeze, such as propylene glycol, or any other medium suitable for the purpose.
  • the secondary cooling medium may be Potassium Formate, a salt based glycol. It has been found by the present disclosure that Potassium Formate as the secondary cooling medium has enabled gain of some significant performance improvements.

  • the first cooling medium being R744 (CO2) refrigerant, there is no phase change from vapor to liquid in the transcritical refrigeration cycle.
  • the first cooling medium passes through a filter drier 17 and into an expansion device 18. Expansion device 18 is shown in FIG. 5 as copper capillary tubing.
  • the first cooling medium that is liquid exits expansion device 18 and enters a primary inlet side of evaporator 101 the first cooling medium expands and evaporates into a mixture of liquid and vapor, the liquid evaporating totally to become vapor as the first cooling medium reaches an outlet of evaporator 101.
  • the first cooling medium that is the vapor returns to compressor 8 to be recompressed in a continuous cycle.
  • the first cooling medium is significantly chilled by the evaporative process of refrigeration system 112, typically to minus 10 degrees Celsius, and this chilling provides cooling energy for the liquid cooled side of refrigeration system 112.

  • lids 200 have lid apertures 202 and pumping and control module 2 and beverage cooling module 3 have module apertures 204.
  • Lid apertures 202 are aligned with module apertures 204 when lids 200 are in place on pumping and control module 2 and beverage cooling module 3, respectively, so that lid apertures 202 and module apertures 204 receive fasteners 206.
  • Fasteners 206, lid apertures 202 and module apertures 204 may each be shaped so that fasteners 206 fit through lid apertures 202 and module apertures 204 in a first position, and, when fasteners 206 are rotated 90 degrees, fasteners 206 do not fit through lid apertures 202 and module apertures 204 to secure lids 200 on pumping and control module 2 and beverage cooling module 3.
  • Pumping and control module 2 may have a depression 208 that fits in refrigeration module 1 so that pumping and control module 2 may be stacked on refrigeration module 1 to provide a cover for refrigeration module 1.
  • Beverage cooling module 3 has latches 110 that mate with mating latches 210 on each of refrigeration module 1 and pumping and control module 2 to secure refrigeration module 1, pumping and control module 2 and beverage cooling module 3 together.
  • refrigeration module 1 has refrigeration system 112 that cools evaporator 101.
  • Evaporator 101 is positioned in refrigeration module 1 that cools the second cooling medium that circulates through coolant transfer tubing 14 into heat exchanger coil 6 positioned in tank 5 of beverage cooling module 3.
  • the beverage ingredients are pumped from a beverage ingredient source through pumps 128 to valves 106 on beverage cooling module 3 into cooling coils 4.
  • cooling coils 4 are immersed in tank 5 filled with the cooling medium that is cooled by heat exchanger coil 6 to cool the beverage ingredients for dispense.
  • beverage cooling system 10 in a weight of refrigerant used to charge refrigeration system 112, whilst maintaining the cooling output of a similar sized conventional design.
  • a charge limit of 150 grams is set on all refrigerating equipment in the classification "Category A Occupancies”. Beverage cooling system 10 can fall into this category, and as such is restricted to a maximum refrigerant charge of 150 grams.
  • beverage cooling system 10 the conventional evaporator is replaced with a liquid heat exchanger with heat exchanger coil 6, which may be a copper or stainless steel coil, through which passes, for example, a solution of chilled anti-freeze, which may be a solution of propylene glycol.
  • a solution of chilled anti-freeze which may be a solution of propylene glycol.
  • the transport tubing for the anti-freeze for example, coolant transfer tubing 14, may be flexible plastic tubing, and the joints, for example, valves 106, may be of a quick-release type, for example the "John Guest Speedfit®" design.
  • valves 106 allows the waterbath-based heat exchanger with heat exchanger coil 6 to be isolated from the supply system, thereby permitting the waterbath in tank 5 and refrigeration module 1 to be quickly and easily separated.
  • Refrigeration module 1 can be removed and replaced using one trained operative, who is not necessarily skilled in the art of refrigeration. This may be done independently of the rest of beverage cooling system 10, minimizing the cost of the service call and replacement parts, and the downtime and loss of sales incurred by the end user.
  • Beverage cooling system 10 has the advantage that a single service operative may quickly and easily replace refrigeration module 1 for one more appropriate to the demand, with no downtime to the end user whatsoever. Likewise, beverage cooling module 3 also be easily exchanged for one with a greater or smaller capacity icebank, with minimal downtime, by a single service operative.
  • Beverage cooling system 10 permits a change in refrigerant to be accommodated with virtually no disruption to the end user, and at minimal service cost.
  • Refrigeration module 1 may be disconnected from the remainder of beverage cooling system 10, and a replacement for refrigeration module 1 containing the new refrigerant may simply be connected, by a single service operative, to the remainder of beverage cooling system 10 via the quick release/connect fittings, without the need to exchange complete coolers or melt-back and re-produce icebanks.
  • Beverage cooling system 10 may allow refrigeration module 1 to be disconnected and sited remotely from the remainder of beverage cooling system 10, in an area more suited to its requirements for optimum performance.
  • Flexible insulated tubes would transport the secondary coolant to and from beverage cooling module 3, with electrical extension wires providing a link to refrigeration controls and power source.
  • Beverage cooling system 10 allows just the failed module of refrigeration module 1, pumping and control module 2, and beverage cooling module 3 to be removed from the remainder of the main assembly of beverage cooling system 10 and returned, thus saving a substantial amount of factory space, or permitting a higher volume of parts awaiting repair to be stored in the available space.
